Cautions：

1. While using RS485 communication, if it’s the end inverter, then need to connect end resistor (Jumper J3);

2. To avoid outer interference to the communication signal, suggest use twisted-pare shielded cable on the

communication connection, avoid parallel cable.

AppendixB：HV580L Modbus communication

HV580L series inverter provides the RS485 communication interface, and support the Modbus RTU - from

standing communication protocol. Users can through the computer or PLC central control, through the

communication protocol Setting frequency converter running commands, modify or read function code

parameters, read the inverter working condition and fault information, etc.

1. Protocol content

The entire message frame must be used as a continuous stream. If the pause time frame prior to the

completion of more than 1.5 byte times, the receiving device will refresh the incomplete message and

assumes that the next byte will be the address field of a new message. Similarly, if a new message starts in

less than 3.5 bytes times following the previous message, the receiving device will consider it a continuation of

the previous message. This will set an error, as the value in the final CRC field will not be valid for the

combined messages. A typical message frame is shown below.

192

Application mode:

The inverter accessing with “single main multi-slave” PC/PLC control network, which equipped with

RS232/RS485 bus.

Bus structure:

(1)Interface mode

RS232/RS485 hardware interface

(2)Transmission mode

Asynchronous serial, half-duplex transmission. At the same time host and slave computer can only permit one

to send data while the other can only receive data. Data in the process of serial asynchronous communication

is in the message format and sent one frame by one frame.

(3)Topological mode

In single-master system, the setup range of slave address is 1 to 247. Zero refers to broadcast communication

address. The address of slave must is exclusive in the network. That is one condition of one slave machine.

Communication information structure

At least 3.5-character time

In the RTU mode, a new frame to at least 3.5 bytes transmission time interval as a start. And then transfer the

data fields in the order: from the machine address, operation command code, data and CRC check words,

each domain bytes are hex 0... 9, A. F. Continuously detect network bus network facilities, including pause

interval of time. When receiving the first field (address information), each network device to decrypt the byte to

determine whether to own. A byte at the end of transmission is complete, and with a 3.5 bytes of transmission

time interval at least to indicate the end of the frame, in the later, can start a new message.

Cyclical Redundancy Check：

Cyclical Redundancy Check—CRC mode: CRC(Cyclical Redundancy Check) is in RTU frame format,

message contains an error-checking field that is based on a CRC method. The CRC field checks the contents

of the entire message. The CRC field is two bytes, containing a 16-bit binary value. The CRC value is

calculated by the transmitting device, which appends the CRC to the message. The receiving device

recalculates a CRC during receipt of the message, and compares the calculated value to the actual value it

received in the CRC field. If the two values are not equal, then results an error. The CRC is started by 0xFFFF.

Then a process begins of applying successive 8-bit bytes of the message to the current contents of the

register. Only the eight bits of data in each character are used for generating the CRC. Start and stop bits, and

the parity bit, do not apply to the CRC.

During generation of the CRC, each eight-bit character is exclusive XOR with the register contents. Then the

result is shifted in the direction of the least significant bit (LSB), with a ZERO filled into the most significant bit

(MSB) position. The LSB extracted and examined. If the LSB is 1, the register then exclusive XOR with a

196

High byte: P0~PF (P group), A0~AF (A group), 70~7F (U group) Low byte: 00~FF

For example: P3.12, the address indicates 0xP30C

Caution:

Group PF: Parameters could not be read or be modified.

Group U: Parameters could be read but not be modified.

Some parameters can not be changed during operation; some parameters regardless of the kind of state the

inverter in, the parameters can not be changed. Change the function code parameters, pay attention to the

scope of the parameters, units, and relative instructions.

Besides, if EEPROM is frequently stored, it will reduce the service life of EEPROM. In some communication

mode, function code needn’t to be stored as long as changing the RAM value.

Group P: to achieve this function, change high order P of the function code address into 0.

Group A: to achieve this function, change high order A of the function code address to be 4.

Corresponding function code addresses are indicated below:

High byte： 00~0F (P group), 40~4F (A group) Low byte: 00~FF

For example:

Function code P3.12 can not be stored into EEPROM, address indicates to be 030C, function code A0-05 can

not be stored in EEPROM, address indicates to be 4005; This address can only act writing RAM, it can not act

reading, when act reading, it is invalid address. For all parameters, command code 07H can be used to

achieve this function.

This parameter is used to set the data transfer rate between the host computer and the inverter.

Caution: The baud rate of the position machine and the inverter must be consistent.

Or, communication is impossible. The higher the baud rate is, the faster the communication is.

Data format

Setting range

1~247，0 is broadcast address.

When the local address is set to 0, that is the broadcast address, achieve position machine’s broadcast

function. The local address is unique (except for the broadcast address), which is the basis for the position

machine and the inverter point to point communication.

Response delay

Default

Pd-03

Setting range

0~20ms

Response delay: It refers to the interval time from the inverter finishes receiving data to sending data to the

position machine. If the responses delay is less than the system processing time, the response based on the

time delay of the system processing time. If the response delay is more than the system processing time, after

the system process the data, it should be delayed to wait until the response delay time is up, then sending

data to host machine.

When the function set to 0.0s, the communication overtime parameter is invalid.

When the function code is set to valid value, if the interval time between one communication with the next

communication exceeded the communications overtime, the system will report communication fault error (fault
